Oz Train Trips

OK, being a worse than terrible flyer you won't see me in here too often, so apologies if I've missed anything along these lines yet.
Has anyone taken the train to Darwin? If so, what were your thoughts?
I always seem to get the Indian Pacific and the Ghan mixed up, but I took one of them to and fro to WA once and had a sensational trip (both there and back) ... Stopped off at Kalgoorlie with some Pommy drinking buddy I met on the trip and it's amazing how many you can throw back in an hour and a half of freedom with a long trip ahead. (He barely spoke to me the next day he looked so crook)
